Curved ceiling structure

ABSTRACT

The present invention relates to a curved ceiling structure, the ceiling structure characterized by having a curved shell shape over the seats of a theater while exposing the screen. Therefore, according to the present invention, structural continuity with the screen curved in horizontal and vertical axes can be ensured, and by ensuring design integrity with the screen curved in horizontal and vertical axes, a sense of immersion can be imparted to an audience and an enhanced life-like sensation can be delivered thereto.

TECHNICAL FIELD

The present invention relates to a curved surface-shaped ceiling structure and, more particularly, to a curved surface-shaped ceiling structure provided in a theater, wherein the ceiling structure is formed in a curved surface type shell shape covering the seats of a theater to expose a screen so that the ceiling structure can secure structural continuity with the screen having curvature in a horizontal axis and vertical axis.

BACKGROUND ART

In general, a movie theater has a structure equipped with a rectangle screen within a building of a rectangular parallelepiped having the surface of a vertical wall, and is fabricated to have a structure that allows audiences to watch visual media within a specific space.

In this case, the rectangle screen has structural problems in that it prevents audiences from securing a sufficient angle of view in watching visual media and a sounding effect which may be felt by the body is greatly different depending on a seat due to the building of a rectangular parallelepiped. Accordingly, various methods are recently proposed in order to solve such problems.

A method for implementing the shape of a screen in a curved surface form is emerging as one of methods for solving the problems. More specifically, in the case of a current IMAX theater, a movie is screen using a curved screen having specific curvature in a horizontal axis.

If such a curved screen is to be used, however, a theater building itself or a structure itself has to be designed so that the curved screen can be installed on the building or structure by taking into consideration the curved surface of a curved screen from the time when a theater is designed. Accordingly, there is a problem in that the curved screen must be newly installed on the existing buildings of a rectangular parallelepiped form or the existing structures for viewing, which have been designed to be suitable for rectangle screens. Furthermore, there are problems in that luminosity of an image is reduced because it is difficult to project an image of constant luminosity on the surface of the curved screen and image content suitable for the curved screen must be separately produced.

Furthermore, there are problems in that a sense of immersion of an audience is reduced and a sound effect does not revive a sense of immersion of the curved screen because the curved screen and the ceiling structure do not secure continuity in structure and are not united in terms of the design.

The present invention has been invented based on such a technological background and also has been invented to satisfy the aforementioned technological needs and to provide additional technological elements that may not be easily invented by those skilled in the art to which the present invention pertains.

FIGS. 1 to 6 are diagrams showing a curved surface-shaped ceiling structure according to various embodiments of the present invention.

As shown in FIGS. 1 to 4, according to the present invention, in the ceiling structure provided in a theater, the ceiling structure CS is formed in a curved surface type shell shape covering the seats ST of a theater T so that a screen S is exposed.

In this case, the screen S is a curved screen and may include a plurality of long-axis members and a plurality of short-axis members. More specifically, the screen S includes the pair of long-axis members formed in a specific direction and spaced apart from each other at a specific interval and the pair of short-axis members formed in another specific direction and spaced apart from each other at a specific interval. The long-axis members and the short-axis members have curvature of a specific size, and the pair of long-axis members and the pair of short-axis members are joined together to have four corners.

That is, the ceiling structure CS is formed in a curved surface type shell shape and can secure structural continuity with the screen including the long-axis members and short-axis members having curvature of a specific size.

More specifically, if the curved screen S is to be installed on an existing building of a rectangular parallelepiped or an existing structure for viewing, a sense of immersion is visually reduced and there is a limit to the transfer of the feeling of movement because the building or structure for viewing and the curved screen S are separated in structure.

In contrast, the ceiling structure CS has a curved surface type shell shape and thus can secure the structural continuity of a curved line with the curved screen S. Furthermore, the curved screen S and the curved surface-shaped ceiling structure CS can be stably installed easily even without a separate change in the design.

Accordingly, the curved surface-shaped ceiling structure CS of the present invention enables an audience to have a sense of immersion and can transfer a high feeling of movement to an audience because it secures a design unity with the curved screen.

Furthermore, an auditory sense of immersion can be enhanced because the homogeneity of a sound quality effect can be sought through the curved surface-shaped ceiling structure.

Meanwhile, as shown in FIGS. 1 to 4, the ceiling structure CS may include a plurality of curved line members 100 formed in a curved line form in a first direction, spaced apart from each other at a specific interval and disposed in parallel and a plurality of binding members 200 spaced apart from each other at a specific interval in a second direction so that the plurality of curved line members is bound together.

As shown in FIGS. 1 to 4, the curved line members 100 of the ceiling structure CS may be continuously disposed to be vertical to a normal direction to the center of the screen and may be continuously disposed in parallel in the normal direction.

As shown in FIGS. 1 and 2, if the curved line members 100 are disposed continuously in parallel in a direction vertical to a normal direction to the center of the screen S, the screen S needs to be exposed. Accordingly, it is preferred that the curved line member 100 is fabricated to have continuous curvature so that a sense of alienation is not generated between an end on the screen side of the curved line member 100 and curvature of the screen S.

Furthermore, as shown in FIGS. 3 and 4, if the curved line members 100 are disposed continuously in parallel in a normal direction to the center of the screen, it is preferred that the curved line members 100 provided on the screen side and the screen S can secure structural continuity by controlling the angle of the curved line members 100 or providing an additional finishing material.

In this case, the ceiling structure CS may include an end member 500 having a shape corresponding top curvature of the screen S, as shown in FIGS. 1 and 2.

One binding member 200 may be continuously bound to three or more curved line members 100. In this case, the binding member 200 may be formed of a curved line-shaped member.

Furthermore, both ends of one binding member 200 may be bound to a pair of the curved line members 100. In this case, the binding member 200 may be formed of a straight line-shaped member having a relatively short length.

In this case, the first and the second directions are not limited to the normal direction to the center of the screen and the vertical direction thereto, and the first and the second directions do not need to be vertically bound together.

Meanwhile, the “binding” defined in the present invention means that independent members remain in contact with each other, and covers meanings, such as attachment, adhesion, coupling, welding, and holding.

Furthermore, the ceiling structure CS may include a plurality of assistant members 300 spaced apart from each other at a specific interval in a third direction so that the plurality of binding members 200 is bound together.

It is preferred that both ends of one assistant member 300 are bound between a pair of the binding members 200. In this case, the assistant member 300 may be formed of a straight line-shaped member having a relatively short length.

One assistant member 300 may be continuously bound to three or more binding members 200. In this case, the assistant member 300 may be formed of a curved line-shaped member.

In this case, the third direction may be a direction parallel to the first direction, that is, the direction in which the curved line members 100 are disposed.

Meanwhile, a finishing member 400 may be coupled to the binding members 200 and/or the assistant members 300.

The finishing member 400 means a panel covering the ceiling structure, and may be divided into a primary curved surface finishing member having curvature with respect to only a one-direction cross section and a secondary curved surface finishing member having curvature with respect to only a bi-directional cross section.

Furthermore, the ceiling structure may have different curvature depending on its position. The size of the finishing member may be different. For example, the ceiling structure may be completed using a simple plane type member not having curvature by disposing the binding members 200 or the assistant members 300 at points having small curvature at a wide interval and disposing the binding members 200 or the assistant members 300 at points having great curvature at a narrow interval.

In this case, if the finishing member 400 is fabricated to have the secondary curved surface, a manufacturing cost is increased, and there is a difficulty in construction because only a specific finishing member designed suitably for a specific location has to be selectively coupled.

Accordingly, as shown in FIGS. 5 and 6, the curved surface-shaped ceiling structure CS of the present invention can form a net type frame structure by binding the curved line members 100 and the binding members 200 and additionally binding the assistant members 300 at the same time. Furthermore, the finishing member 400 can be combined with the curved surface-shaped ceiling structure CS so that it comes into contact with the binding members 200 and/or the assistant members 300.

In this case, economy and the construction ability can be secured at the same time because the primary curved surface finishing member can be used as the finishing member 400.

Furthermore, the finishing member 400 can be directly combined with the binding members 200 without using a separate assistant member 300 because the distance between the binding members 200 forming the ceiling structure CS can be short depending on the size of a theater.

Meanwhile, the curved surface-shaped ceiling structure CS of the present invention may be provided in the theater of a building of a rectangular parallelepiped having the surface of a vertical wall.

In this case, there is a problem in that a howling phenomenon is generated. More specifically, a phenomenon in which an isolated space is formed between the curved surface-shaped ceiling structure CS and the theater T and a sound output by a sound device is refracted and reflected within the isolated space, inputted to the sound device again, amplified and output is generated.

Accordingly, the finishing member 400 may include a plurality of perforations 401. The perforations 401 functions to offset a sound refracted and reflected by the isolated space between the ceiling structure CS and the theater T.

In this case, it is preferred that the finishing member 400 secures fireproof performance within a theater by attaching fireproof sheet paper to the finishing member 400. In this case, various aesthetic factors, such as a wood pattern, may be added to the fireproof sheet paper in order to secure a sense of aesthetic appreciation.

Meanwhile, as shown in FIGS. 1 and 2, the plurality of curved line members 100 may have the same shape. If the curved line members 100 having the same shape are disposed in parallel, a shell structure of a tunnel shape having a curved line with respect to only a one-direction cross section is formed.

In this case, it is economic because the surface of the vertical wall of the theater T is exposed and an entrance and exit and the stairs of the theater can be used without any change. Furthermore, there is an advantage in that the construction ability is improved because the primary curved surface finishing member has only to be used to combine the finishing member 400.

In this case, structural stability can be secured because an end on one side of the curved line member 100 can be disposed to come into contact with the bottom. In this case, an opening portion 600 is formed by removing portions of the binding members 200 coming into contact with the bottom, and a projector or an entrance and exit may be formed in the opening portion 600 in order to secure functionality.

In this case, it is preferred that a metal reinforcement structure frame is additionally installed to dispose the projector in the opening portion 600.

Furthermore, as shown in FIGS. 3 and 4, the plurality of curved line members 100 may be disposed to have height gradually lowered toward one side or both sides based on one curved line member.

Accordingly, a dome-shaped shell structure having a curved line with respect to the bi-directional cross section is formed. In this case, only the screen S of the theater T is exposed, but the surface of a vertical wall is not exposed, and thus an opening portion, such as a separate entrance and exit, has to be formed. In this case, a construction cost is slightly increased, but independency from the theater can be maintained. Accordingly, there are advantages in that structural continuity with the screen can be secured and a sense of immersion can be enhanced visually and aurally.

In this case, since both ends of the curved line member can be disposed to come into contact with the bottom, hanger members 700 to be described later are simplified, the construction ability can be secured, and structural stability can be easily sought.

In general, an existing theater has been constructed in form in which a screen is mounted on a building of a rectangular parallelepiped or a structure for viewing. In contrast, according to the present invention, as shown in FIG. 3, in the theater T equipped with the curved surface-shaped ceiling structure, the ceiling structure CS is formed in a curved surface type shell shape covering the seats ST of the theater T so that the screen S is exposed.

Accordingly, the curved surface-shaped ceiling structure CS can be disposed easily and stably within the theater even without a separate change in the design.

The ceiling structure CS may be fixed by beams, that is, the upper structures of the theater T, or the hanger members 700 provided in a gutter. The hanger members 700 may be combined with the curved line members 100 or the binding members 200 and fixed thereto.

The hanger member 700 may include a spacer 710 coupled to the curved line member 100 or the binding member 200 orthogonally and a hanger pipe 720 coupled to the spacer 710 in a vertical direction. In this case, a hollow type metallic pipe may be preferably used as the spacer 710 and the hanger pipe 720. The spacer 710 and the hanger pipe 720 may be coupled using various known methods, such as welding or bolting.

In this case, the hanger pipes 720 may be disposed at intervals of 1,200 mm using angular pipes of 1.4T mm in 50×50 standard. A shaded bracing may be provided on both sides of the hanger pipe 720 in order to secure structural supplement so that the hanger pipe 720 is not fluctuated by vibration or a load. In this case, an angular pipe of 1.4T mm in 30×30 standard may be used as the bracing.

Furthermore, a theater equipped with the curved surface-shaped ceiling structure of the present invention may include all of the characteristics of the curved surface-shaped ceiling structure, and a redundant description thereof is omitted.

Meanwhile, as shown in FIG. 7, a ceiling structure construction method for constructing a ceiling structure in a theater according to the present invention includes the steps of (a) disposing the plurality of curved line members 100 formed in a curved line form in the first direction in such a way as to be spaced apart from each other at a specific interval, (b) separating and disposing the plurality of binding members 200 in the second direction at a specific interval so that the plurality of curved line members 100 is bound together, and (c) combining the finishing member 400 with the binding members 200.

In this case, at step (a), it is preferred that the curved line members 100 are disposed by lifting and need to be fixed in the state in which the degree of horizontality and the degree of verticality have been set.

Furthermore, at step (a), the hanger members 700 are provided in the upper structure of the theater T, and the curved line members 100 may be fixed to the hanger members 700. As described above, the curved line members 100 may be coupled to the binding members 200.

Meanwhile, according to an embodiment, at step (a), the plurality of curved line members 100 has the same shape, and an end on one side of the curved line member 100 may be disposed to come into contact with the bottom. In this case, it is preferred that the curved line member 100 is coupled to the bottom through anchor bolts. Structural stability can be secured by additionally coupling the hanger members 700.

Furthermore, according to another embodiment, at the step (a), the plurality of curved line members 100 may be disposed to have height gradually lowered toward one side or both sides based on one curved line member 100.

In this case, it is preferred that the height and distance of an adjacent curved line member 100 are designed by taking into consideration curvature of the ceiling structure CS. The curved line member 100 may be disposed to have both ends come into contact with the bottom.

Meanwhile, at step (b), the plurality of assistant members 300 may be disposed in the third direction in such a way as to be spaced apart from each other at a specific interval so that the plurality of binding members 200 is bound together. In this case, at step (c), the finishing member 400 may be combined with the binding members 200 and/or the assistant members 300.

Furthermore, the plurality of perforations 401 may be formed in the finishing member 400. The perforations 401 can function to offset a sound refracted and reflected by an isolated space between the ceiling structure CS and the theater T, thus being capable of effectively removing a howling phenomenon.

As described above, those skilled in the art to which the present invention pertains will understand that the present invention may be implemented in other detailed forms without changing the technological spirit or essential characteristics of the present invention. Accordingly, the aforementioned embodiments should not be construed as being limitative, but should be construed as being only illustrative from all aspects. The range of right of the present invention is disclosed in the appended claims rather than the detailed description, and it should be understood that all modifications or variations derived from the meanings and scope of the present invention and equivalents thereof are included in the scope of the appended claims.
